Demonstration by heavy-meromyosin of actin microfilaments in extracted cress (Lepidium sativumL.) root statocytes

摘要

When statocytes of cress root-caps were incubated in an extraction medium containing phalloidin, bundles of microfilaments (6.6±2.4 nm in diameter) were found in the cortical cytoplasm. The inclusion of heavy-meromyosin in this medium demonstrated an arrowhead pattern on the filaments indicative of the presence of actin
